Thanks, moneyB! In some parts of the video you can see that the lines (shapes) are very visible in mountain grey and polar silver. In white - and especially in red - the lines disappears. Try to stop the video at about 41 seconds, when the cars are standing together. Then you can see it clearly. I'm still considering red, but it is may be too bright.
AMG Boost had a great suggestion that we sticky a thread that contains posts/pictures from owners of their brand new CLA's... So, without further delay, here it is! Post pictures of your brand new CLA in this thread.
